Successful data recovery of broken eMMC chip MCU1

jumper to quartz

as in, shorting across the oscillator, or something else?

Back on page 18, laurs makes a good picture of shorting the oscillator (jumper to quartz)

Yeah I eventually went through and saw that, thanks

If anyone has info on downgrading or otherwise installing a firmware image without root, but with rw to the eMMC, please PM me. I'm on 2021.24.28-40 and need to get down to something rootable.

No idea what's wrong with this MCU, but it's no longer booting. Black screen. Was working, dumped the eMMC in-circuit, now no boot. Not sure if it's hardware or firmware that's the issue.

Anyone have 2021.24.28-40 they could DM me?

Anyone have a diagram for flashing CID's Spansion in circuit?

 

[cloneguru]

Not that I’ve seen.

Well, before I do any more soldering, I’m gonna poke around with Fusee and see what I can find out. I did a lot of ****ery with the Nintendo Switch way back, maybe that’ll be of some use with this Tegra.

I was successful with the Nintendo but not here

I'm happy to find this thread, nice to see how many MCU1 are still on the road. I also looking for a 2021.24.28-40 or similar image for testing, can you help me ?

Hello to all. Can anyone send me a working IC firmware dump 2021.24.28-40 and 2022.8.10.11 for Tesla Model S
Tanks in advance

Has anyone got a list of spansion chip images that correspond to each firmware numbers? I bet not, but would be nice to have

 

[Zeemo]

or maybe iis there a way to trick the spansion to happily hanshake with the emmc, if I change a small amount of data on it?

Hi, Can anyone share with me a 2022.8.10.5 firmware ?

Very thanks ...
